EVALUATION OF YIELD AND SEED REQUIREMENTS STABILITY OF BREAD WHEAT(Triticum aestivum L.) VIA AMMI MODEL

Abstract

High quality seed of wheat is the key to successful agriculture. Improvement and evaluation of agronomic traits have been the primary objective of breeders for many years under variable environments. The objective of the present research was to determine influence of genotype, environment and their interaction on yield and randman of seed as a seed quality represent and to evaluate stability through AMMI model. Grain samples were obtained from ten winter wheat cultivars grown in 2009/10 and 2010/11 at three locations in Serbia: Novi Sad, Sremska Mitrovica and Pančevo. Yield and randman of seed were investigated and statistically analized via AMMI model which shows significant differences between genotypes at various locations. Best performer was Simonida with average yield 8.22 t·ha-1 . Analyses of randman of seed indicate at differences in the main effect and interaction.
